I won't play coy, I've got one. Used it for the first time yesterday, and it's everything I expectedit to be. Used it during my leg workout, and did sprints outside in between sets. That thing is no joke with the current settings I have. HOWEVER, it is loud as FUCK when you're gasping for air indoors. Since I was the only person in my workplace gym at the time it didn't matter...but I know for sure you'd get massive stares anywhere else.
